The 2(C6H5COO)5Cl(C4H8O2)]·2.5C4H8O2, consists of two NdIII ions bridged by one Cl− ion, five benzoate ions and one coordinating 1,4-dioxane molecule. One NdIII ion is nine-coordinate, with a very distorted monocapped square-antiprismatic geometry. It is coordinated by two chelating carboxylate groups, three monodentate carboxylate groups, one chloride ion and one dioxane molecule. A second independent NdIII ion is eight-coordinated in a distorted square-antiprismatic geometry by one chelating carboxylate group, five monodentate carboxylate groups and one chloride ion. The chains of the extended structure are parallel to the crystallographic b axis. There is a small amount of void space which is filled with five disordered dioxane solvent molecules per The intensity contribution of the disordered solvent molecules was removed by applying the SQUEEZE procedure in PLATON [Spek (2009). Acta Cryst. D65, 148–155].

Benzoic acid was purchased from Aldrich and used without further purification. Nd(OiPr)3 was purchased from Strem and used without further purification. 1,4-dioxane was distilled onto molecular sieves from potassium benzophenone.
Benzoic acid (0.366 g, 3 mmol) was dissolved in 1,4-dioxane (20 ml). Solid Nd(OiPr)3 (0.321 g, 1 mmol) was added and the solution was refluxed overnight. The solution was allowed to cool to room temperature and then filtered. The filtrate was concentrated and single crystals were grown upon cooling of this
to room temperature in a hot water bath over the course of several days. Crystalline yield 0.069 g (11.14%) calculated based on Nd.Hydrogen atoms were included in idealized geometries riding on the atom to which they are bonded. Aromatic C–H distances were constrained to 0.95 Å and methylene C–H distances constrained to 0.99 Å. All hydrogen thermal parameters were set to 1.2 × Ueq of the carbon to which they are bonded.
Disordered solvent could not be reliably modeled and was thus omitted from the model through the use of SQUEEZE (Spek, 2009). The void space analysis yielded a volume of 540 Å3 with an electron count of 224, located at a center of symmetry. This corresponds well to five molecules of dioxane per
The atom count has been corrected to reflect this solvent inclusion.Data collection: APEX2 (Bruker, 2008); cell

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes. |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger. |

We are interested in building three-dimensional materials using pre-assembled molecular aggregates as secondary building units (SBUs) linked through ditopic organic molecules (Morris et al., 2008). The title compound was synthesized with this goal in mind. However, instead of forming neodymium-benzoate SBUs which could be linked through 1,4-dioxane, a 1-D neodymium-benzoate polymer was crystallized. The closely related compound [Nd2(C6H5COO)6(CH3OH)4] was previously reported as a 2-D material from PXRD data(Nayak et al., 2010).
The asymmetric unit consists of two Nd3+ metal centers bridged by one Cl- ion, five benzoate ions and one coordinated 1,4-dioxane molecule (Figure 1). The presence of chloride can be explained as carry-over from the synthesis of Nd(OiPr)3 which is synthesized from NdCl3 and NaOiPr (Andersen et al., 1978). The extended crystal structure is a 1-D polymeric chain composed of Nd/Cl/carboxylate interactions. The dioxane solvent molecule acts as a terminal donor. The 1-D chains extend along the crystallographic b-axis (Figure 2). Small channels also run along the crystallographic b-axis and are filled with disordered solvent molecules. The solvent could not be reliably modeled and was omitted through use of the SQUEEZE routine within PLATON (Spek, 2009; see refinement procedures for details).
Nd1 adopts a 9-coordinate distorted mono-capped square anti-prismatic geometry. It is coordinated by two chelating carboxylate groups, three monodentate carboxylate groups, one bridging chloride ion and one terminally coordinating dioxane molecule. Nd2 is 8-coordinate in a distorted square anti-prismatic geometry. It is coordinated by one chelating carboxylate group, five monodentate carboxylate groups and the bridging chloride ion.
